13 Some qcom based bootloaders identify the dtb blob based on a set of
14 device properties like SoC and platform and revisions of those components.
15 To support this scheme, we encode this information into the board compatible
16 string.
17
18 Each board must specify a top-level board compatible string with the following
19 format:
20
21 compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]"
22
23 The 'SoC' and 'board' elements are required. All other elements are optional.
24
25 The 'SoC' element must be one of the following strings:
26
27 apq8016
28 apq8074
29 apq8084
30 apq8096
31 msm8916
32 msm8974
33 msm8992
34 msm8994
35 msm8996
36 mdm9615
37 ipq8074
38 sdm845
39
40 The 'board' element must be one of the following strings:
41
42 cdp
43 liquid
44 dragonboard
45 mtp
46 sbc
47 hk01
48
49 The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor>
50 where the minor number may be omitted when it's zero, i.e. v1.0 is the same
51 as v1. If all versions of the 'board_version' elements match, then a
52 wildcard '*' should be used, e.g. 'v*'.
53
54 The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9.
55
56 Examples:
57
58 "qcom,msm8916-v1-cdp-pm8916-v2.1"
59
60 A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version
61 2.1.
62
63 "qcom,apq8074-v2.0-2-dragonboard/1-v0.1"
64
65 A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in
66 foundry 2.
